Hey all, I am having an issue with port forwarding OpenVPN on 192.168.11.12:1194/udp. I suspect it may be an issue with my firmware, Tomato 1.28 downloaded from ( Polarcloud/tomato ).

WRT54GL is my router, and up until a few days ago I had DD-WRT running on it (build 14939). The wireless would constantly perma-drop after making a new setting change until I reset the device and reloaded the old config file or tried reconfiguring manually. Such a pain! However now Tomato has taken its place and I'm mostly happy to have made the switch. The wireless problem has vanished (perhaps b/c Tomato runs lower tx power) and, except for port forwarding, everything is pretty stable.

Is there a later version of Tomato that is appropriate for the old WRT54GL? I see TomatoUSB spun off from the original project, and now there are community builds being released on this forum. I'm happy the development continues, but finding stable firmware for my older device seems difficult.

I have searched and can find no one else that is having the same port forwarding issue, however on the following linked forum page 'raptor17' suggested that the interface OpenVPN uses (tun11) may not be correctly referenced in iptables therefore causing the disconnect.

OpenVPN service is running on my target host 192.168.11.12. I have used Zenmap to query the machine and indeed the service is running on port 1194/udp ( nmap -sU -p 1194 192.168.11.12 )
